Answer:
True
Explanation:
An atom's valance electrons are those electrons that have the highest energy. Atoms tend to be stable and nonreactive if they have the highestvalence electrons. In the periodic table, the number of valence electrons in each element decreases from left to right across each period.
As per Einstein's theory of relativity we know that when an object will move with the speed comparable to the speed of light then the length of the object will be different from its length at rest position
This is also known as length contraction theory
As we know here that

so here we know that
v = 0.95 c
so from above equation we will have


so here the length will be SHORTER
A circuit breaker is an automatic device for stopping the flow of current in an electric circuit as a safety measure.
A magnetosphere is the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.
Hope this helps!! All credit goes to Google though
Answer:
2. electromagnets can be made stronger by adding more coils to the solenoid.
3. electromagnets can be made stronger by increasing the strength of the electrical source.
Explanation:
Electromagnets are not permanent, they act as magnets when current runs through its coils. They can be stronger by increase the current that goes through the coil surrounding them,. This can be done two ways: 1) increasing the actual current intensity, or 2) increasing the number of coils that wrap around them.
Answer:
The angular velocity is
Explanation:
Generally the acceleration experienced by the propeller blade's is broken down into
The Radial acceleration which is mathematically represented as

And the Tangential acceleration which is mathematically represented as

The net acceleration is evaluated as

Now since angular speed varies directly with angular acceleration so when acceleration is maximum the angular velocity is maximum also and this point if the propeller blade's tip exceeds it the blade would fracture
So at maximum angular acceleration we a have
